The thesis and pump.fun feeds return newest first and page with a before cursor.
  • before is an item id, not a timestamp. It returns items older than that id. Omit it for the newest page. An unknown before returns 400.
  • Each page carries hasMore and nextBefore. nextBefore is the oldest item’s id, and null on the last page.
  • On the thesis feeds, limit sets rows per page, 1 to 100, default 20. The price is per started block of 20 requested rows. pump.fun callout pages hold 25 and take no limit. count reports how many came back.
  • A page can come back empty. Ask again on your normal interval.

Dedupe keys

The same thesis can be issued again under a new id and a later post time. thesisHash stays the same. It is built from the author, the trade, the token and the thesis text, and is null when one of those is missing.

​
Following a feed

Call without before on a timer and drop what you have seen, or hold a WebSocket. Ask on a fixed interval of a few seconds or more, not in a tight loop.
